Question

Find side b if side a = 10 inches and side c = 16 inches.Round to the nearest hundredth if the answer is uneven

Answer 1

If you are talking about a triangle do the Pythagorean Theorem.


a^2+b^2=c^2


10^2+b^2=16^2


100+b^2=256


b^2=256-100=156

b=√156

b=12.5

Answer 2

Hopefully, you're talking about Pythagorean theorem.

a^2 + b^2 = c^2

They gave us side a and side c, so we plug in our values

10^2 + b^2 = 16^2

You solve the exponents

100 + b^2 = 256

Subtract 100 on both sides

100 + b^2 = 256
-100 - 100
You're left with:

b^2 = 156
You square root both sides

b = 12.489...

We round and get our final answer:

b = 12.49

Good luck!
